Application filed August 17, 1925. Serial lo. 50,634`

lli y invention relates to building construction and the like, such as interior walls or partitions of 'dwelling houses and other buildings. I aim to provide a convenient and economical substitute for wooden or expanded' metal la'thing such as heretofore used for the base of plastered interior walls.

In suitable forms of emluuliulcnt, my invention allows the walls-to be more quickly constructed reduces the time and labor rcquired in plastering and in the erection of the base for the plaster; reduces the amount of plaster required; renders the wall waterproof; and makes it slower burning.

In carrying out my invention as hereinafter described, I provide the wall with a bituminous covering mineralized or sur- .faced with suitably coarse, adherent mineral granules Ssuch as particles of crushed stone, slag or tie like),I and apply thereto the plaster that is to form the exterior of the wall. The bituminous covering may consist of superticiall mineralized bituminated fabric, and may secured directly to the main wall structure or frame-work, such as the usual upright studding, braces, fetc. In the drawings, Fig. I isa mental-y view of a wall embodying .my invention, with various exterior layers partly broken away to illustrate various features in the construction of the wall.

Fig, II shows a Section of the wall on Va larger scale than Fig. I.l

The `wall here shown is constructed with a framing of upright wooden studding 5 and horizontal wooden braces 6 between said uprights. On the frame-work is secured the bituminated fabric covering 7, shown as consistin-g of felt or paper 8 (see Fig. H) satu- 40 rated withv bitumen and also coated therewith on oneV or both 'sides as at 9, and surfaced with small stone granules 10 embedded -in the bituminous coating 9 of onev face.

For this covering 7 may be employed prevpared tooling such as now on the .markenpreferably a .roofing surfaced with rather Coarse mineral granules 10, that will give it an effective tooth to hold plaster. The material 7 may be applied in stri nailed directly tothe frame-work, and its joints (both longitudinal and transverse) are preferablyv lapped and bituminouslyV cemented (if absolute water tightness is desired), to aford a continuous moisture-repellent and water-proof covering. Preferably, the strips ot material extend vertically, and are of slightly greater width than the spacing of the studding 5, (or correspond approximately in width to a multiple of such spacing), so that the strips may be lapped and nailed to the studding along both margins, as shown at 1l. In practice, the materiali' is also nailed as at l1 to all other members of the wall structure which it covers, such as the horizontal members 6. Any joints in the strips are preferably made at the cross bracing G between the studding, so that they may be lapped and nailed to such bracing. In the absence of cross bracing where these joints fall, however7 the lap ends of the strips may be tied or sewn together with wire, as at 12, to afford temporary stifenirg.

The bituminaied fabric 7 having been applied to the wall structure as described, the usual rough coat of plaster 13 (brown coat) is applied directly to its granular surface 10 and allowed to Set, so as to stitfen the fabric base for the application of a finishing or other subsequent plaster coat or coats. The stiffness thus afforded allows the subsequent coat or coats to be applied with all necessary force without flexing they fabric base. The fabric 7 should, of course, ybe secured atan ample number of widely distributed points, to enable it to sustain the weight of the plaster 13. Y v p This form of construction effects a. great economy in the amount of plaster used in walls, because no excess to key into or through the base 7, as in the case of wooden or expanded metal lathing. The labor yof applying the flexible fabric is much less than that of applying wood laths, and the use of wood in the wall is minimized. Vith bituminous fabric of suitable composition, or treated'with suitable sub` stances during manufacture, the wall is slower burning than if constructed with wood laths. Owing to the watcr-proof character of the bituminous fabric 7, moreover, a water leak in, behind, or above a wall or ceiling thus constructed will not reach the plaster and stain it or canse itto fall, as is the case with lath and plaster construction.

VHaving thus descri my invention, I claim: 1. An interior wall construction compris ing, in combination with the main wall plaster is required lstructure or studding, a covering of bitumen saturated and coated fabric, mineralized with adherent granules, secured to said Wall structure; and a covering of plaster interlocked with said granules.

2. An interior wall construction comprising, in combination with the main wall structure or studding, a covering of bitumen saturated and coated paper or felt vsurfaced with adherent coarse mineral granules nailed 10 to said wall structure, and a covering of plaster applied and adhering directly to said granules.

In ytestimony whereof, I have hereunto signed my name at Philadelphia, Pennsyl- 15 Yania, this 14th day of August., 1925.
